Abstract:This study aimed at evaluating performance and egg quality of Japanese quails fed feeds containing different corn and limestone particle sizes. A total number of 648 birds in the peak of production was distributed in a random complete block experimental design, using a 2x3 factorial arrangement (2 corn particle sizes and 3 limestone particle sizes). Birds were designated to one of two blocks, with six replicates of 18 birds each. Mean geometric diameter (MGD) values used were 0.617mm and 0.723mm (corn fine and… Show more
“…The differences observed for FCR (Table 5) between the treatments were not statistically significant (P>0.05). The average values of FCR obtained in this study in terms of kg feed consumed to produce dozen eggs were comparatively higher than those reported by Berto et al, (2007) for Japaese quails (0.39 kg/dz) fed with feeds containing different corn and lime stone particles. This may be mainly due to adoptation of mixed sex rearing system during the experimental period.…”
The proximate composition, pepsin digestibility, gross energy and macro mineral contents of 12 composite samples of poultry offal meal produced in Sri Lanka were analyzed. The average dry matter, ash, crude protein, crude fiber, ether extract, in vitro pepsin digestibility and gross energy of poultry offal meal were 92.

“…The best egg-laying rates obtained in the present study were 81.67%; 86.67% and 88.33% respectively for GD 3, LD 2 and LD 3. These results corroborate those of [45]; [46]; [47]; [48] as well as [49]. These authors indeed obtained laying rates between 82% and 89.36% during a laying period of eight weeks (from the sixth to the fourteenth week).…”
In Côte d’Ivoire, the quail breeding is confronted with the lack of food specific to the species. Thus, in the south-east of this country, an experimental study was conducted at the ISMOREL farm in the sub-prefecture of Adiaké. This study, which aims to improve the productivity of day-to-day farms, focused on the grain size of the feed. From grower (GD) and layer (LD) diets, 5 experimental diets have been manufactured. There are: LD 5 with a particle size of 5 mm, LD 3 and GD 3 with a particle size of 3 mm as well as LD 2 and GD 2 with a particle size of 2 mm. The growth parameters related to 750 two-week-old unsexed subjects weighing 49.67 ± 0.17 g on average. For egg-laying, 300 female quails were used at 6-week-old. The results showed an influence of the 2 mm grain size (LD 2 and GD 2) on parameters such as feed intake (186.96 ± 4.73 g and 153.46 ± 5.33 g), average live weight (142.37 ± 1.76 g and 155.85 ± 1.85 g), the average daily gain (4.29 ± 1.22 g/d and 4.74 ± 1.25 g/d), the age of first egg laid (49.33 ± 0.58 d and 46.33 ± 1.26 d) and egg-laying rate (67.24 ± 30.97% and 74.12 ± 34.03%). At the end of this study, it appears that the 2 mm particle size induces better growth and egg-laying performance in Japanese quail.
“…Indeed, the synergistic action resulting from the association of several protein sources in the A3 food has already been demonstrated by many researchers including Smith [33] who showed that various protein sources lead to better performance of spawn subjects. The daily egg laying rates obtained in quails in this study are lower than those obtained by Marques et al [34], Berto et al [35], Hassan [36] and Abdel-Azeem [30]. who worked respectively on quails during a period ranging from the 6 th to the 14 th week.…”
The effects of the consumption of formulated (A1, A2 and A3) and commercial (AT) feeds on the zootechnical and nutritional performance of quail (Coturnix japonica) were studied. The experiment involved 80 1-day-old quails. At the end of the experiment which lasted 9 weeks, the quantities of food ingested per day by quail A1, A2, A3 and AT were respectively 25.27±0.02 g, 25.34± 0.08g, 23.83±0.11g and 23.85±0.08g. A3 and AT quails had the highest mass gains with respective values of 3.65±0.22 and 3.64±0.17 g/d. The best feed efficiency after the growth phase was observed with quail fed with growth feed formulated A3 (6.52 ± 0.05). The carcass yields of the quails fed with the formulated growth foods A1, A2, A3 and commercial AT are respectively 63±0.01; 66±0.01; 64±0.03 and 64±0.03%. The highest mortality rate (10%) was found with quails fed A1 and A2 formulated growth feed. In short, among the formulated feeds, feed A3 had a better impact, similar or even greater than that of commercial feed AT on the zootechnical performance of the Japanese quail studied.
